TERRO Ant Dust Powder Killer for Indoors and Outdoors - Kills Ants, Fire Ants, Roaches, Spiders, and Other Insects - T600 - Up to 8 Months Protection - Easy to Use

Needed this and worked . Best stuff for anything and not harmful to pets. Fast delivery and unexpensive and nicely packaged. We had lots of ants when we moved into our new house outside our house and we bought this and it worked and now there is no more ants or bees.

I had a stubborn ant problem outside that seemed to be getting worse by the day. I applied the TERRO T600 Ant Dust around the problem areas in my yard, and I started seeing results almost immediately. Within 24 hours, the ants were either gone or clearly on their way out. I’ve also noticed fewer spiders and other bugs hanging around, which is a great bonus. The powder is easy to apply and doesn’t have a strong or lingering smell. I love that it works on so many types of insects, and the 1lb size goes a long way for outdoor use. If you’re dealing with ants or other pests outside your home, this stuff works. I’ll definitely be keeping this in my pest control arsenal from now on.

This powder worked great on a few big ant hills in my yard. When I went to mow 1.5 weeks later (after we got rain), the powder was still present and no ants could be found. For the money, I would like for there to have been more powder in the size tube it came in, but otherwise I had no issues with spreading it or how long it lasted.

My husband was in shock that finally something works on these flippin’ buggers! we have tried everything! from straight 30% vinegar, to natural concoctions to malathion, to ortho & other proclaimed ‘effective’ products… the little piles of sawdust or dirt whatever the brown sugar looking hills were, kept reappearing within 48 hrs.. well, after shooting down Terro’s liquid ant bait inside the house traps that didn’t work whatsoever in my bathroom!!! i didn’t realize this dust for the crack where the driveway meets the garage was from the same manufacturer! i barely shook any out of the container last night — a very very light dusting! (see pic) well…at first my husband thought it had just attracked more & it looked like it by the massive quantities that must have came out of the crack! until i said … omg! they aren’t moving! they are dead!!!! at least a thousand or more, DEAD with one light dusting application! happened overnight in less than 24hrs.. the few anys that were moving were just twitching! (almost felt sadistic watching the remaining alive ones suffer, but they sure didn’t care how they terrorized us for years!) i would highly recommend this product!!! & it’s waterproof. altho’ i wouldn’t let my husband hose them away for a few hrs.. i intend to redust ever so lightly again because i tend to be anal when it comes to bugs. great purchase for a reasonable price!

I've used Terro in a couple of my homes, and it does what it claims: Gets rid of ants. It doesn't work overnight. The ants have to take the powder back to the nest so others eat it and eventually die. In the meantime, there are ants which don't eat it right away and continue to appear in the house. Eventually, though, usually within a week, no more ants! It saves calling an exterminator.

It worked well for the first few days but it looks like after a while the ants changed their diet and started to walk around freely again.

This stuff works! Our warehouse in an industrial area is swarming with sugar ants. We have professional pest control and they couldn't get rid of them. Their treatment killed them by the tens of thousands, but there were just as many to replace them. They seemed to be after moisture as we were in a drought. I tried Maple syrup and borax which works well. Killed them by well, but still more kept coming. Ordered the stick in the ground bait traps by same company. Put them close to the hole under the foundation where I think the colony is. They emptied 4 traps in a day. They still kept coming. Ordered the DuPont gel bait. They didn't touch it. Tried some powder by the front door where they were swarming. Next day, they were gone. Not an ant in sight. Put powder around one side of the building (they were entering from two sides). Completely shut them down. Put some powder in our second (unused) warehouse where they were swarming. Checked 2 days later and traffic was reduced by 75% and dead ants everywhere. Put some around the warehouse rest room that we were literally filling a dust pan a day of dead ants. Next day, none were present. I found their main entry point to the colony and nuked that hole. Only a few survivors walking through it the next day. I have pretty much surrounded the perimeter of the building. I found maybe a start of a new colony in the parking lot and dusted that area. In conclusion, this stuff works. I am not sure if they are avoiding the area or have simply died off. Evidence kind of suggests both. I just walked though the 5000 sq ft. warehouse and saw on ant. Everything else (except the gel bait) killed them as well, but did nothing to keep them out or diminish them. I will keep vigilant and make sure that they don't come back with this trusty powder. The picture is what the floor of the bathroom looked like every morning. Update. Amazon listing says 1 pound, but I have ordered it twice now and received 2 pounds each time. Also, take the waterproof claim with a grain of salt. We had a decent rain last night and a lot of it washed away. Still keeping my 5 star rating however.

Worked well. Difficult to control application. Would be great for dusting application though.
